Meet The Doctors


Dr. Lisa McDonald, DMD

Dr. Lisa McDonald graduated from Southern Illinois University School of Dental Medicine in 2001 and since that time through advanced studies, teaching, and full time private practice, she has developed a remarkably high level of clinical proficiency. She brings with her a wide variety of services including clear aligner therapy, surgical procedures, and implant services, along with the same excellent preventative and restorative care that you deserve. Dr. McDonald has recently become certified in “Vivos” sleep apnea treatment and is passionate about helping all of her patients breathe well and find comfortable treatment for sleep apnea. Dr. McDonald approaches patient care in a caring and compassionate manner. She always puts the patient first and treats everyone like members of her family!


Dr. McDonald is a member of the American Dental Association, the Missouri Dental Association, as well as the Greater St. Louis Dental Society. Dr. McDonald lives in Des Peres and enjoys spending time with her daughter Ava.  Cycling has become a fun hobby and passion and Dr. McDonald loves exploring all of the great St. Louis trails.
